As the upper OTPs are ECC protected, they support only one 32 bits word programming. For a second modification of this word, these ECC become invalid and this OTP will be no more accessible, the shadowed value is invalid. This patch adds a warning to indicate an upper OTP update, because this operation is dangerous as OTP is not locked by the driver after the first update to avoid a second update.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
